What strains are used to make biological fermented feed

Biological fermented feed has developed rapidly in recent years and has made great contributions to the breeding industry. Many large-scale breeding companies, many feed companies, have begun to produce, and use fermented feed, fermented soybean consumption and other fermented products.


What kind of bacteria are used in fermented feed? What are the application methods of microbial inoculants for feed? What are lactic acid bacteria, bacillus, and ethereal bacteria?


The catalogue of microbial species for feed released by the Ministry of Agriculture and Rural Affairs has seven categories, namely lactic acid bacteria, bifidobacteria, bacillus, yeast, mold, photosynthetic bacteria and propionic acid bacteria. 

There are three types of common bacteria used in actual production, namely lactic acid bacteria, bacillus and yeast. They are mainly used for drinking water, mixing and fermented feed for poultry, etc., aiming to improve the intestinal flora of animals, improve immunity of animals, and improves the digestion and utilization of feed, while reducing waste excretion and odor excretion, realizing source emission reduction and reducing the pressure of manure treatment.


What are the application methods of feed microbial inoculants? 

Feed microbial inoculants are divided into direct feed inoculants and fermented feed inoculants. 

The number of effective viable bacteria for direct-fed inoculants is as high as possible, while fermented feed inoculants require fermentation activity to be as high as possible. 

Fermentation activity means that the inoculation is easy to activate, the inoculation into the fermentation raw material grows rapidly, the conversion speed of the raw material is fast, and various fermentation indicators are suitable. 

Direct feeding inoculants are divided into liquid preparations and solid preparations. The use of fermented feed inoculants can be divided into inoculants for fresh fermented feed and dried fermented feeds according to their activity. 

According to the source of raw materials, they can be divided into It is an inoculant for full fermented feed and feed material fermentation.


What is lactic acid bacteria? What are its characteristics and applications? 

Lactic acid bacteria is a general term for bacteria that can ferment carbohydrates and produce lactic acid. 

It is anaerobic or facultative, gram-positive, without spores, and widely present in the intestinal tract of animals. 

It is a bacterium that often lives in the intestine of animals and has important physiological functions. 

Lactic acid bacteria have the characteristics of acid and bile salt resistance and strong adhesion. They are the earliest, most widely used and most diverse probiotics in animal production. 

However, lactic acid bacteria are not tolerant to high temperatures and are easily inactivated during feed processing and storage. Lactic acid bacteria are widely used in biological fermentation feed and microbial feed additives.


What is Bacillus? What are its characteristics and applications? 

Bacillus is a kind of aerobic or facultative, gram-positive, spore-producing, and probiotic. Bacillus exists in the form of endophytic spores. 

It has the characteristics of acid resistance, bile salt resistance and high temperature resistance. Bacillus is generally a "passing bacteria" in the animal body and can secrete many enzymes and other beneficial biomass. 

For example, Bacillus subtilis can secrete a variety of extracellular enzymes such as amylase, protease, lipase, cellulase, and lecithin, and can also produce a variety of vitamins, which can improve feed utilization. 

Bacillus can inhibit the growth of intestinal pathogenic bacteria, regulate the balance of intestinal flora, prevent digestive tract diseases, and improve the body's immunity. 

It plays an important role in the fields of microbial feed additives and bio-fermented feeds.


What is yeast? What are its characteristics and applications? 

Yeast is a single-celled fungus, which can survive in both aerobic and anaerobic environments. It is a facultative anaerobic microorganism with poor thermal stability and an acidic environment with polysaccharides. 

It can metabolize to produce a variety of nutrients, which are scattered in the animal intestine. Yeast has nutritional properties, regulates intestinal balance, promotes host immune function and many other probiotic effects. In particular, yeast cells are rich in protein, nucleic acid, vitamins, and polysaccharides. A variety of active enzymes can provide nutrition for animals, so it is widely used in fields such as microbial feed additives and bio-fermented feeds.


In the actual fermentation process of fermented feed, according to the different raw materials, different fungi should be properly selected for fermentation. 

The various bacteria should be synergized and inhibit each other, and finally achieve the effects of degrading fiber, improving feed digestibility, and improving animal immunity.

The Paragon company has always followed the characteristics of each strain to give customers appropriate recommendations, and provide excellent equipment to ensure that customers produce the highest quality feed products.
